Miami-Dade County detectives last week, during a rather routine pot investigation, discovered a rather bizarre setup: A laboratory containing 82 live cannabis plants, in a concrete underground crawl space only accessible through a bedroom hatch.

The plants were hidden at the bottom of a swimming pool which had been sealed at ground level with concrete. The only way into the chamber was through a hatch door in a bedroom that led to the crawl space, which ended at the base of what used to be a swimming pool.

The discovery came after detectives from the department's narcotics bureau approached a car on Jan. 23 outside a home at 30121 SW 147th Ct., and found several bags of marijuana. After getting consent to enter the home, police said, they found the open hatch that led to pot chamber.
